PEORIA, ILLINOIS, A CORPORATION. i

IRONING MACHINE.

To all 10 /Lom t may concern.'

Be it known that I, EDGAR L. YORK, a citizen of the United States, and a resident of Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Ironing Machines, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to machines for ironing various kinds of clothing and other cloth, and it has for its objects to simplify the arrangement and construction of the machine whereby its operation may be properly controlled; and whereby the machine may be operated either by hand or power, and when operated by power its operation may be instantly started or stopped without the necessity of stopping the motor for operating the machine; and whereby when the machine is in operation, a constant pressure of the heating element will be maintained upon the work passing through the machine; and whereby the ironing element will be selfcentering in its relation to the feed roller; and in other features of construction which together with the novelty of my invention will be hereinafter more fully set forth and specifically pointed out in the claims.

In the accompanying drawing:

Fig. 1 is an end view of a machine embodying my invention.

Fig. 2 is a front view of thesame.

Fig. 3 is a sectional end view of the ironing element.

Fig. 4 is an enlarged detail partly in se'ction of the clutch for disengaging the feed roller.

Fig. 5 is a detail view of a hand crank and pinion for hand operation of the machine.

The same numerals of reference are used to indicate identical parts in all the figures.

In its preferred form of construction my machine comprises a pair of legs G upon which a receiving table 7 is mounted, the latter carrying the brackets 8 and 9. Feed table 10 is carried by the upper' portion of the brackets 8 and 9 and the feed roller 11 .is suitably j ournaled in these brackets.

The ironingelement 12 is provided with trunnions 13, which pass through the upper ends of bell cranks 14 which 1n turn-'are con- Specification of Letters Patent. Fanghi-,ed Jan. 17., 1922s Application filed September 22, 1919.

Serial No. 325,495.

nected through rods 15 to crank arms 16 mounted on a rock shaft 17, the latter being provided with a foot treadle 18.

A tension spring 19, is connected to each bell crank 14 and to the brackets 8 and 9, these springs exerting their tension to move the upper ends of the bell-cranks, and with them, the ironing element 12, toward the feed roller 11.

It is to be noted that the linkage from the bell cranks to the foot treadle is such that when the treadle is released the ironing element recedes from the feed roller. A ,pair of lugs 2O are carried by the ironlng element and at each end thereof and located one on each side of the bell cranks 14, the lugs being spaced part to allow a limited oscillating motion of the ironing element 12 so that it may properly center itself against the feed roller 11, the lugs 20 serving to prevent the ironing element from turnlng in either direction on its trunnions beyond a predetermined amount.

To cause the operation of the feed roller, one of its trunnions is provided with a driving gear 21 (Fig. 4) the gear 2l carrying clutch jaws 22 adapted to be engaged by jaws 23 of clutch hub 24 which is splined on the outer end of the trunnion, the clutch being shown disengaged in Figs. 2 and 4. A shifter 25 is operated by connecting rod 27 which extends to the handle 28, the latter being preferably mounted on the under side of the feed table 10 (Figs. 1 and 2).

The gear 21 is engaged by a worm 29 carried by shaft 30 which is driven by sheave 31 over which the belt 32 passes, the belt also passing over the sheave of the motor- 33, the construction and arrangement of part-s just described being such that when the motor 33 is set in motion, the clutch 24 may be operated to start or stop the feed roller 11.

Should it be desired to operate the feed roller by hand( the same may be accomplished by removing the Worm 29 and the shifter 25 and placing the pinion and crank 34 (Fig. 5) upon the stud 35 (Fig. 1) whereupon the gear 21 may be operated, the clutch 24 being left engaged with the gear 21 and the operation started or stopped by merely turning or releasing the crank 34.

Any suitable burner or heating device 36 may be employed to heat the ironing element. To give access to the interior of the heating element for the purpose of inserting the burner or heater and to afford proper ventilation for the combustion chamber, I provide the rear face of the ironing elevment with a removable portion 37 which may be provided with a series of openings and which may extend through the greater length of the ironing element, the construction of this feature of the device being shown in Fig. 3.

The feed roller 11 is preferably covered with a cloth or other facing so that its frictional engagement with the work passing through the machine will be sufficient to movethe work through the machine.

The operation of the machine is as follows.

After having lighted the burner in the ironing element, the operator depresses the treadle 18 and causes it to engage one of the notches 38 (Fig. '2) thereby holding the ironing element away from contact with the feed roller until its temperature has been raised to that desired for the work to be performed. The motor 33 and its connected gearing is next set in motion and a quantity of work arranged on the feed table 10 where upon the lever 28 may be operated to engage the clutch 24 and cause the rotation of the feed roller 11 and the work on the feed table 10 fed toward the roller 11 whereupon the treadle 18 is released from the notches 38 thus permitting the ironing element to assume, through the action of the springs 19, its proper working position.. As the work passes through the machine it is collected upon the receiving table 7 from which it may be removed to `any suitable place and as the supply upon the table 10 is exhausted the treadle 18 is again depressed until a new supply is secured.

Should it occur that a portion of the work is passing through the machine improperly, the clutch of the feed roller may be disengaged whereby upon this action, the work may be pulled out of the machine and the clutch again 1re-engaged and the Work fed through in a proper manner.

Should it be desired to handle work of an excessively heavy nature or of a plurality of thickness of cloth the work may be carried through a machine in a step by step manner by operating the clutch through its connec-` tions as previously described, the clutchbeing engaged and disengaged periodically, to permit the ironing element to rest for a time again against any desired portion of the work. i

It is to be observed that the ironing element is provided with a concaved face of approximately the same radius as the radius of the feed roller thus providing a large contact between the ironing element and the work handled by the machine.

Having thus fully described my invention, I claim:

1. In an ironing machinethe combination of a frame comprising in part feeding and receiving tables, and a Vwork feeding element mounted adjacent the feeding table, clutch controlled driving mechanism for the` feeding element, a concaved-face ironing element mounted adjacent the work feeding element, trunnions for carrying the ironing element, movement limits restricting the oscillating motion of the ironing element upon its trunnions, means for yieldingly holding the ironing element against the feed roller, and means for overcoming lthe latter means to move the ironing element away from the feed roller.

2. In an ironin machine the combination of a frame comprising in part a work feeding and a work receiving table, a feeding roller mounted adjacent the feeding table, means for operating the feed roller, a concavedface ironing element, trunnions for mounting said element adjacent the feed roller and for moving it toward oraway from the roller, movement limits for controlling the oscillating motion of the ironing element on its trunnions, means for normally' pressing the ironing element toward therfeed roller, and foot operated means for moving the ironing element away from the feed roller.

3. In an ironing machine the combination of a frame, a feed table carried thereby, a

feed roller carried by the frame and adjacent the feed table, a pair of bell-cranks carried by the frame, springs for moving the upper ends of the bell-cranks toward the feed roller, a foot pedal and connections to the bell-cranks to overcome the springs and move the upper ends of the bell-cranks away from the feed roller, and an ironing element pivotally mounted at each 0f its ends to the upper end of each bell-crank and cooperating with the feed roller when the foot pedal is released.
